OPERATION
Sensitivity Adjustment
The "H" has been factory set for most shower applications. However, if the fan is in a tub area or is being used for dampness control, the "H" may
need to be increased toward maximum "+". If the control is responding too often to changing environmental conditions, movement toward less "-"
"H" may be required. To adjust the "H":
1. Disconnect the power at service entrance
2. Through the grille, locate the slot marked "H"
3. Carefully rotate the "H" adjustment toward "+" or "-"
4. Turn ON power and check operation by turning on the shower or other humidity source until the fan turns on
5. Repeat above steps if necessary. When the temperature changes, humidity sensor values will have deviation
Timer Adjustment
The humidity sensing fan has a "T" (means timer) that can be adjusted from 5 to 60 minutes (factory-set at about 20 minutes).
This controls the length of time that the fan remains ON after the sensor has stopped sensing a rise in humidity and the humidity level is below the
user-adjustable set point. To adjust the "T":
1. Disconnect the power at service entrance
2. Through the grille, locate the slot marked "T"
3. Carefully rotate the "T" adjustment to desired setting
4. Check the operation by turning ON a humidity source until the fan turns on
5. Turn humidity source off and time the unit
6. Repeat above steps if necessary
Fan with ADD on Motion Sensor Grille
The fan and motion sensor can be operated separately. See the wiring
diagram on page 4 of this instruction manual for details.
Sensing distance will be impacted of the body's own situation (for
example, the thinner people wearing the more remote sensing distance).
Turn on the switch sensor system begins working, the fan run
continuously at a pre-set lower level. When entering the gesture area fan
will run at the certified airflow rate, indicator light turns on.
When person leaves, indicator light turns down, the fan remains working
until the delay time (3-30 minutes) has passed, and then the fan is
transferred to the pre-set lower level. Installation distance is 7-9ft.
Sensing range is within the cone angle of 90º
Fan with ADD on Speed Controller
Use a 2 function wall control. See the wiring diagram on page 4 for details.
Set the motor speed as you need.
Max airflow is HVI certified performance based on HVI procedures 915, 916 and 920.
Other airflow reference performance based on HVI procedures 915, 916 and 920.
Fan with ADD on Light Kit and Night Light
Use a 3 function wall control. See the wiring diagram on page 5 for details.
